To all whom it may concern:

Be it known that I, CHARLES Gr. CUSH- MAN, a citizen of the UnitedStates, residing at New York, in the county of Kings, State of New York,have invented certain new and useful Improvements in LubricatingDevices; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to an improvement in lubricating devices, andwhile devised particularly for use on the bearings of grinders employedin the paper making industry can be used in other relations, where aconstant feeding of oil to a journal is desired, and more particularlywhere the rotating parts are heavy and frequent inspection of thejournal is desirable.

More particularly, the invention relates to that type of lubricatingdevices in which the oil is fed from an oil receptacle to the journalbymeans of material through which the oil flows by capillary attraction.

7 One of the objects of the. invention isto provide a device of thischaracter comprising a plurality of oil feeding members extending fromthe oil receptacle to the journal, and so arranged that the number ofactive oil feeding members may be readily increased or decreased toregulate the amount of oil supplied to the bearing.

A further object is to provide for convenient inspection of the journalwhile the machine is in operation to ascertain Whether or not it isbeing properly lubricated, or is becoming out or grooved by the presenceof foreign material in the bearing. 1

Another feature of the invention is the simplicity of the means forretaining the oil feeding members in position while at the same timepermitting the same, either singly or ,as a group, to be easily andquickly removed from contact with the journal or placed in workingposition thereon. This retaining means also permlts ready withdrawal ofthe feeding members from the oil receptacle, either for renewal orrepair, as occasion may require.

In the accompanying drawings, illustratmg one embodiment of theinvention-Figure 1 1s a sectional view, somewhat diagrammatic, of thelubricating device, this section bemg taken on the line 1-1 of Fig. 2;and Fig. 2 is a plan View thereof.

In the drawings, the journal 3 is rotatably supported on a bearing 4: ofany standard design, the box here shown being but illustrative and inlarge measure diagrammatic. A cap 5 is removably secured to bearing 4 bybolts 6. Cap 5 is open at the top, as shown, to afford access to thelubrieating means and to permit ready inspection -of the journal forascertaining whether it is being properly lubricated and is in otherrespects in good working condition.

Removably positioned within cap 5, and adjacent the rear Wall thereof,is'an oil receptacle 7 open at the top and of substantially the samelength as the opening in the cap, but of lesswidth than said opening, sothat it will overlie a portion of the journal 3, as illustrated inFig. 1. The front wall 8 of the oil receptacle terminates below the topof cap 5, but the rear Wall 9 is extended upwardly and is bent back overthe edge of the cap to form a supporting hook 10. This constructionprovides for the ready removal of the receptacle through the top of thecap for purposes of cleaning and repair, or if for any reason it isdesirable to inspec't the entire surface of the journal thus exposedwithin the cap.

The oil is fed from receptacle 7 to journal 3 by means of a plurality ofstrips 11 of felt, or other suitable material, through which the oil mayflow by capillary attraction. Preferably these strips are formed bycutting into the edge of a sheet of the felt, or like material, and theother or uncut edge of the sheet is secured in the oil receptacle by alead weight 12 placed thereon or fastened thereto. The free ends of thestrips rest on the downwardly moving portion of the journal surface, andconvey to it the oil which they carry by capillary attraction out of theoil receptacle. The weight need not be attached to the receptacle andmay at any time be lifted out should it become necessary of oil which isfed to the journal can be regto replace or clean the strip, or gainaccess to the entire upper half of the journal.

WVhen an inspection of the journal is desired, the ends of some or allof the trailing strips can be lifted to expose the moving metal beneath,and, if it be found that too much oil is being fed to the journal," someof the strips can be lifted and folded back into the oilreeeptacle, andso be out of action. In this way an easy regulation of the oilconsumption is made possible. Should it be necessary for any reason toinspect the entire upper surface of the journal, the oil receptacle andits attached strips can be lifted out through the top of cap 5.

The employment of a plurality of oil feeding strips engaging the surfaceof the journal has several advantages over the use of a single padextending the entire length of the surface to be lubricated. The amountulatedwithout the aid of mechanical clamps or other similar control ofcapillary action, and if it should be found that one part of the journalis running hotter than the remainder, the number of strips at the hotend may be increased to feed more oil to that particular part withoutsupplying an excess of oil to other parts of the journal. If one of thestrips becomes charred or glazed with dirt, it can be folded back or cutoff and another strip be put into action to take its place. Furthermore,as each strip is comparatively narrow, and not likely to be deprived ofits regular supply of oil, and

not liable to wedge against the shaft, there is little danger that itwill become charred or burnt. In this respect the present device offersmany advantages over any construction wherein a single pad or oilingstrip is used. Ordinarily, not all of the strips shown in Fig. 2 will bein action at any one time, and if a half or a third of them are inaction, and the others folded back into the oil receptacle, it is ofcourse possible for the operator. to look down through the gaps and'seewhether the journal is running wet or dry, and whether the number ofstrips should be decreased to save oil, or increasedto save wear on thejournal and bearlng.

' I/Vhat I claim is:

i 1. The combination of a bearing, a jourmoval from contact with thejournal without disturbing the others, thereby to regulate the place andquantity of oil delivered and facilitate inspection of the journal whilerotating.

2. In a lubricating device, the combination with a journal to belubricated, of a bearing therefor, a cap for said bearing having anopening exposing the top part of the journal, an oil receptaclepositioned in said openingand removable from said cap to permitinspection of substantially the upper half of the journal and a sheet offelt having one edge dipping into the oil and its other edge out into aplurality of strips which are adapted to trail on the journal, each ofsaid strips being capable of removal from contact with the journalwithout disturbing the others.

3. I11 a lubricating device, the combination with a journal to belubricated and a bearing therefor, of a cap secured above said bearingand having a longitudinal opening exposing substantially the upper halfof said journal, an oil receptacle in said open ing and secured to oneside of said cap, said. receptacle being removable through the top ofthe cap, and a sheet of oil feeding felt immersed at one edge in the oilof said receptacle and at its other edge out into a plurality of stripswhich trail on the receding surface of the journal and are removabletherefrom independently of one another to regulate the quantity of oilsupplied to the journal.

4:- The combination of a journal and bearing therefor, of a cap securedto said hearing and open at the top, an oil receptacle positioned insaid opening, and a plurality of oil-carrying members receiving oil fromsaid receptacle and delivering it to said journal, each of said membersbeing removable from contact with the journal independently of theothers to thereby regulate the quantity of oil supplied to the journal.

5. The combination with a journal and a bearing therefor, of an oilreceptacle positioned above said journal, a weight therein, a pluralityof lubricating members held by said weight with one end immersed in theoil of said receptacle and the other end trailing on the journal, saidmembers being independent of one another andcapable of being lifted outof contact with the journal without disturbing the other members.

6. The combination with a journal and a bearing therefor, of a capsecured to said bearing and open at the top to expose a large portion ofthe top of said journal, an

oil receptacle suspended in said opening by engagement with one side ofthe cap, a weight in said receptacle, a strip of suitableoil-transporting material having one edge secured within said receptacleby said 1,181,997 y y m weight, and its other edge out into a phi--rality of strips adapted to trail on the rotating journal, saidoil-transporting material being arranged to carry oil upward over theedge of said oil receptacle and deliver it to the rotating journal, eachof the strips being capable of removal from contact with the journalwithout disturbing the others, thereby to regulate the place andquantity of oil delivery and facilitating in- 1Q spection of the journalWhile rotating.

In testimony whereof I alfix my signature.
